Log Message:
Push CBC-MAC and CCM block updates into the aes_impl API.
This should help reduce the setup and teardown overhead (enabling and
disabling fpu, or expanding bitsliced keys) for CCM, as used in
802.11 WPA2 CCMP. But all the fiddly formatting details remain in
aes_ccm.c to reduce the effort of implementing it -- at the cost of a
handful additional setups and teardowns per message.
Not yet implemented by any of the aes_impls, so leave a fallback that
just calls aes_enc for now. This should be removed when all of the
aes_impls provide CBC-MAC and CCM block updates.
